PARDON POST, OF HAVEN, CONNECTICUT.V

MODE 0F FASTENING BEDSTEADS.

Speccation of Letters Patent No. 780, dated J' une 12, 1838.

To all whom t may concern:

Be it known that I, PERDON Pos1', of the city and county of New Haven, State of Connecticut, have invented a new Improvement in Fastenings of Bedsteads; and I do hereby declare that the following is a full and exact description.

Instead of the mortise tenon and screw, I use four metallic plates of equal and sufficient thickness orthe requisite strength.

Plates C and D are connected together by a neck, the whole being cast in one piece, and are screwed on the side of the post, see Figure 1. Plate C has one or more parallel dovetails on the to which are to lock into plate A. Plate A, ig. 2 is screwed fast on the end of the rail, (and is calculated to be of the same size) has a mortise through the center of it suliiciently large to receive plate C through it. It has also one or more dovetail spaces on the upper part of proper size to match the dovetails of plate C, thus forming a parallel dovetail lock. It has also an opening in the lower part of the plate to receive the neck which connects and makes part of plate C and D. Plate B Figs. 2 and 3 is screwed fast on the underside of the rail, has two dovetails which are placed on Vthe lower edge of plate A forming a dove tail space which receives the neck of plate C and D. Plate C D has two dovetailed spaces at D to match or receive the dovetails of plate B which are locked together at right angles. Plate C D is placed into the mortise of plate A and the rail settles down, thus forming a close joint supported by three or more dovetail locks'.

I do not claim as my invention the locking of bedsteads by dovetail wedge joints; but

What I do claim is- The addition of plate B, having the two dovetail tenons fitting into the lower part of plate C, D, at D, the whole being con-4 structed and combinedsubstantially as herein described.

In witness whereof I hereunto subscribe my name this 16th day of January 1837.
